ABSTRACT:
A method of and an installation for packaging in a sterile medium employs a composite film constituted in a thermoplastic film in which containers are formed, and a covering film with their opposing faces sterile. These are separated at the entrance to a sterile enclosure in which the containers are formed and filled, in a sterile atmosphere, the thermoplastic film forming the lower wall of the enclosure. The full containers are covered with a strip from which lids are formed without the inside of the containers being able to be contaminated, and the covering strip and thermoplastic film are connected in an air-tight manner. The method and installation are particularly suitable for packaging perishable food products, in particular dairy products.
